j i MACHINE FOR APPLYING FAPEB FLIES TO BOXES. A 'i l Application led December 15, 1911.

per Flies to Boxes, of which the following is -a specification.

This invention has reference to improvements in machines for'applying paper flies to boxes, and its object is to provide a machine by means of which paper flies may be expeditiously attached to boxes to which latter a cementing material has already been applied, the present invention being designed to opera-te in conjunction with the machine for .preparing boxes for the application to flies thereto disclosed in my application No. 621,402, tiled April 15, 1911, although the present machine may be used in conjunction with other machines for apply ing paste to boxes or for other purposes.

In accordance with the present invention there is provided a holder for a stack of flies whether plain or lace, that is, perforated with some ornan'iental design, and devices are arranged in such manne-r that a box having an interior strip of paste therein may be placed upon the top member of the Stack of flies and pressed thereagainst, after which other devices will hold the remaining flies of the stack so that when the box is removed more than one fly will not be removed with it.

The presentl machine is preferably of the manually operable type, although this does not preclude the use of power if so desired.V

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying` drawings forming part of this specification, with the understanding, however, that while in the drawingsthere is shown a practical embodimentof the invention, the latter may be embodied in other forms differing in structural details from that shown in the drawings, and hence the invention is by no means limited to any exact conformity with the showing of the drawings, but may be changed and modiied so long as there is no material departure ...Showing the parte .in alle operatvepgsiaep,

Fig. 3 is a section on the line 3 3 of Fig. 1 with thc parts in the same position indicated in Fig. 2. Fig. 4 is Aa section in the same plane as Fig. 3 but showing the parts in another operative position. Fig. 5 is a bottom plan view with thesupporting legs and actuating bar in cross section. Fig. 6 is a section on the line (56 of Fig. 1, but drawn to a larger scale and omitting distant parts and also some adjacent parts. Fig. 7 is a perspective View of the fly engaging fingers and some adjacent part-s.- Fig. 8 is a detail section on the line 8 8 of Fig. 2. Fig. 9 is a detail section on the line 9 9 of F ig. 2.

Referring to the drawings, there is shown a table l of appropriate size and usually rectangular in outline, although any particular shape is of no moment. The table is supported upon a frame 2 of suitable form, whereby the table is raised to a suitable height above a support, such as a floor, to facilitate the operation of the machine. Of

course, the frame 2 may be replaced by any suitable supporting means and the table 1 may form part of a larger structure and may be constructed of skeleton form for lightness and the saving of material.

Considering the structure as composed in the main o-f the table 1 and support 2, one long edge of the table hasa drop portion 3 extended beyond the supporting frame 2, whereby there is formed a ledge l and a shoulder 5, the ledge serving as a support for a series of blocks 6, each with one edge 7 beveled and each block is traversed by a screw 8 entering an undercut channel 9 where the screw receives a nut 10, so that 'l Athey form an overhanging support projectinglaterally from one long edge, but all the blocks together do not extend when placed in side contact the full length of the table,

so that there remain spaces for the insertion of other blocks 11, each of which is formed with a marginal flange 12 at substantially right angles to the block 11 along one edge thereof, and these blocks 11 may be placed at the ends of any associated number of blocks 6 to form guide flanges for apurpose which will presently appear. The blocks 6 ,in arranged that when in Position @a the' ledge 4 they Will have What may be termedthe upper surface flushA with the top-of the table 1.

Mounted on the table 1 is af guide 13 halving extended from one face a slotted arm 14 adaptedl to lrest ontop of the table 1 and the slotl of this arm is traversed by a bolt 15 having a milled nut 16 orv other suitable means whereby the guide may be adjusted toward'Y or from the margin oit the table con-4 taining the hlocks 6 toazny desired extent. By this' means 14there maybe supported upon the' table pile of flies 17, the latter being either plain vflies or of the perforated variety, fand the guide 13 is so adjusted that oneJ edge of the pile Will be even with the outer' edges of an associated group of blocks l 6, such groiip being usually arranged intermediate of the ends of the table and Hanking' p the two blocks 11 with npstanding anges 12 enfibraeingl the corresponding edges of the pile or stack of flies, but the upstanding anges 12 are so related, to the blocks 11 and blocks' 6 that they are located an appropriate distance back from that edge ot the pile of flies coincident Wit-h the outer edgeof the group of blocks 6'. j

Near ,what may be termed the rear edge of thetable, that is, the edge remote from the blocks 6, there' is secured to the table a block 18V on which' is formed a' pair of spaced ears' 19!A designed to receive a pivot pin 2O ra'versing saidu ears and a hub' 21 formed on a lever 22 the longer arm of which may be slightly ciiri'fed, as indicated, and the shorter arm 23 of rvhich is v,arranged at an angle to the longer arm, although such angular disposition is not mandatory. The longer of t'lielever 22 adjacent the hub 21 is formed with a slot 24 receiving cue end of a barv 25, held tothe lever by a pivot pin 26. The bar 25 is passed through :inappropriate slot 257 in the ytable 1 and to nea-r the bottoni ot the table Where it is pivotally' connected ,to a treadle lever 28 conveniently placed for manipulation by the footof an operatori standing about midway of the length. of the table in front of the portion of the table providedv vvith` the blocks .6 and which portion of the table may, therefore, be termed the front of the table. The lever 22 extends to a point ad- A jacentthe front edge of the table and is there bifurcated, as vshovn at I29, and this bifurcated portion is traversed by a pivot pin 3 0 also extending through one end of a link 31 in depending relation tothe lever and vat the other end pivoted bvV a pin 32 betvveen ears 33 ony an angle bracket 34 fast to a bar 35, vvhich latter is of a length somewhat less than the length of the table 1, although 4so far as this operation is concerned it maybeyas ong asthe table or longer, if desired. r., bar has, near its ends sockets 36 extending a Substantially fight angles to the'length of the bar 35 and each socket receives one end of yan arm 37, which arm may be in the form of atlat bar having i.the end remote from the socket 36 formed with a longitudinal slot 38, such slot being traversed by a screw or pin 39 carried by a bracket 40 fast to the table 1, While extending from the bracket 40 to a pin 41 on the j arm 37 is a spring 42 tending at all times to move the arm 37 in the direction or its length toward ,the bracket 40. The movey mentof the arms 37 irn'der the action of the roller 43 to move the respect-ive arm 37 against the action otl the spring 42 in one direction of movement of the parts and to y permit the` spring 42 to act to move the respective arm 37 as the parts move in the other direct-ion, these several movements being for a purpose Which Will presently appear.

Underneath the table there Ais a pair of parallel spaced hangers 47 traversed by pivots 48, 49, respectively, for levers 50 and 51, respectively, the pivots 48 and 49 being shown as kformed of bolts, but:I it Will be understoodthat they may be"4 otherwise constructed. The levers 50 and 51 are arranged Isubstantially beneath the lever 2'2 and eX- tend in substantially the same direction, that is, from the front to the rear of the table.` To permit the passage of the manipulating bar or rod 25, the lever 50 has a slot 52 formed therethrough and the lever 51V has a slot 53 formed therethrough, rvhile the bar 25 is traversedby a pin 54 so positioned as l to. engage the lever 51 for a purpose Which Will presently appear. At a llotver pointthan the pin 5 4 the ba'r 25 is traversed by another pin 55 to Which are attached the corresponding ends ot tivo springs 56 on opposite sides ofthe bar 25 and these springs are in turn attached to eyes 57 Which may be formed onthe under face of the table 1, the purpose of the springs 56 being to raise the bar 25 and with it the lever 22 and parts carrier thereby When the treadle 28 is not depressed by the :toot of the operator.

The lever 50* at the end adjacent the slot 52 carries a Weight 58 and the leverr 51nd jacent the slot 53 carries a Weight 59, these Weights tending constantly toturn the levers about their pivots in one direction. The

Weighted end of the lever 50 pivoted to Y in the table .1 to a point above the same and,

tending between the wings of the shorter Varm of` the lever `22 is provided with a longitudinal slot 62 traversed by a pin 63 carried by the shorter arm 23, so that-the lever 22 may have a range of movementwithout affecting the link 60. That end of the lever 5()` remote from the weight 58 extends to a point beneath the drop portion 3 of the ltable and is there appropriately bifurcated, as indicated at 64, and at the extremities of the bifurcations is traversed by a rod 65 extending beneath the overhang 3 and about the front thereof, and of a length to carry a plurality of fingers 66. These ngers ,are shown in the drawing as threein number, although not limited to such number and each finger is shown formed intermediately with a bend 67 and terminates in a hook portion 68. The fingers are adjusted along the rod 65 by means of set screws 69 while one finger is mounted between the wings of the bifurcated end 64 of the lever 50 and is provided with parallel ears 70 extending from the axis of the rod 65 in a direction opposite the corresponding finger 66. The ears 70 are traversed by a pivot pin 71 in turn traversing one end of a link 72, the other end of which is connected by a pivot pin 73 to the corresponding end of the lever 51.

In order to describe the operation of the structure of the present application it is necessary' to consider 'that there is provided a supply of boxes 74 each of which has applied thereto, usually on one inner wall adjacent the open edge of the box, a suitable layer of paste which is customarily in the form of a long narrow band ofV paste which may be placed on the box by the mechanism and in the manner described in my aforesaid application. It is assumed that the boxes 74 reach the operator working the machine of the present invention with the paste still moist enough to be sticky.v The normal position of the parts may be assumed to be substantially that shown in Fig. 4, the springs 56 raising the bar 25 until the front end of the lever 22 is elevated and the rear end of the arm 28 is depressed, the arms 37 being drawn rearwardly by the springs 42. Assuming that there is a stack 17 of flies on the table, the follower 13 and guides 12 having been properly adjusted, the lingers 67 will engage by their hook portions or noses 68 over the corresponding outer edge of the stack 17. This is brought about by the action of the weight 58 and the lifting action of the pin 54 on the lever 51. The weight 58 causes a lowering of the corresponding end of the lever 50 and the rais- .ing of the front end. thereof lifting the Series of` lingers 66until` their hook ends 68 are above Ithe top of the stack of flies, while at the same time the lifting action ofthe pin i 54 on the rear end of the lever 5 causes a corresponding lowering of the` front end thereof and thence through the links 72 rocks the rod 65, thusmoving the fingers 66 toward the table 1 until arrested by the front edges of the blocks 6 then in the path of the lingers. The movements are so timed that the series of fingers are lifted until the noses 68 are above the stack of flies before these fingers are moved toward the table, and after the fingers are brought into engagement with the blocks 6 the combined action of the levers 51 and 50 then force the noses 68 into engagement with the corresponding portions of the flies.

An operatorplaces a box with the open i portion toward the table until the box has the pasted side in overhanging relation to the stack of fiies, and further movement of the box toward `the table is arrested by the engagement of the box with the overhang 3 on each side of the series of blocks 6 sustaining the corresponding portion of the stack of flies. The operator on depressing the treadle 28 causes a llowering movement of the forward end of the lever 22 against the action of the springs 56. The downward movement of the bar 25 permits the weight 59 to act on the lever 51 which at vonce swings the series of fingers 66 away from the front of the table, so that the hooks or noses 68 move out of the pat-h of the box 74. The continued downward movement of the bar 25 `and lever 22 finally brings the rollers 43 into engagement with the beveled portions 46 of the upstanding members 44 and these beveled portions act to cause a forward movement of the arms 87 against the action of -the springs 42. This movement causes the bar 35 to be-brought into contact with the then upper side ofthe box and forces it into intimate engagementwith the uppermost fly of the stack, causing the iiy to adhere to the box by reason of the sticky paste on the box. rThe downward movement of the lever 22 ust described ultimately brings the pin 68 into engagement with the upper end wall of the slot 62 of the link 60 and the rear end of the lever 50 is raised, thus depressing the front end thereof and moving the' fingers 66 still farther away from the stack of flies and out of the path of the box 74, this movement taking place as the bar 35 is approaching the stack of flies. The position of the parts during the compression of the box against the topmost fly is shown in Figs. 2 and 3.

The operator now releases the treadle 28` when the contraction of the springs 56'immediately raises the bar 25 and by this the lever 22 is also raised. This causes an cleration .O f the barand under the action loc los
